Try a current choke 'balun' instead of the BL2.
As a temporary antenna I have 25m of twin speaker wire run out from the
shack under the roof tiles - that's about 7m - and then the remaining
18m split as a doublet. It hangs at an average height of 5m from a
couple of trees. The 'feeder'

Thanks to both for info and assistance. You were right Don about the

It turns out that the sensitivity issue was caused by a tiny solder bridge

I agree that the BL2 is a true current balun using a balanced design

ease a conjugate match - albeit one of the ratios is 1:1 - but my

Just out of curiosity...
Where was that solder bridge on the MC1350? Was it already on the SMD
assembly when you received it, or was it something you caused by your
soldering?
The reason I ask is that I had a problem with my SMD MC1350, never found out
what caused it, and just replaced it. If
It was actually one of your earlier posts (thanks!) that prompted me to

As to when the solder bridge got there... I'm not 100% certain that a bridge

If this had been an offshore rig, you would have had to send it to a
factory authorized repair facility for warranty work. Since there was
no fault, you would have had to pay a service charge and shipping both
ways. Another advantage of buying an Elecraft rig.

It still says that new orders are targeted for 4 months. I ordered my K3 kit
on April 11th and I wonder if the 4 months will hold meaning it arrives in
August or will it be closer to the 6 months of the rigs now arriving meaning
October? No complaints but just curious.
And a tad bit anxious ;)
I had never thought about the quality of a serial number, but I
suppose having serial number 911 should give me pause.

You may remember I have a problem with my K3 whereby dropping the
